Can someone explain to me why this page has a content warning? I'm not trying to start an internet flame war, I'm just legitimately curious what in this page is graphic or offensive.

I''m just guessing, but it may be that the way the action is framed may be too much for victims of abuse. We mostly see Target alone; this creates a very point-of-view experience which could trigger traumatic memories in those that have been in a similar situation themself. If we had more of an outside perspective (by seeing more of Thistle too), I think the scene would not necessitate a warning.The same scene from an outside point of view would probably be okay, but I guess we all know the main reason why it's framed the way it is; so regarding that I think it was a sensible choice to put on a warning. It may require an extra click by everyone, but I think that's worth it for the people that need that warning. (Kinda like the forum having the option to switch to a dyslexia friendly font; few people need that, but that's no good reason to not include it for those that do.)
